added air to my tires.

It depends what you consider over inflating. If you consider going higher than the car manufacturers recommendations, you're wrong and if you consider going a bit over the max sidewall on newer tires you're wrong. If you mean going to 100+ psi or something like that, you may be right.

There is a growing number of people who inflate to maximum sidewall pressure and beyond with no ill affects and loads of various benefits like better MPG, handling, braking etc. Any statements to the contrary are made by people who do not know the facts.

My latest pair of winters have been at a constant state of 50 psi or more and same goes for my current all seasons. I have over 40,000 combined kms on these tires and they still exhibit virtually no wear. Inflating to maximum sidewall and a little higher has only one downside and that is ride comfort, anyone telling you any different either doesn't know what they're talking about or is a liar.

Voodoo,
Thanks! I'm glad to know that Yokohama has wasted tens of thousands of dollars and countless hours training me on tire manufacturing, tire construction, tire conditions and more. I could have saved my company TONS of TIME AND MONEY if I had just come here and asked you about the "facts"...

By the way: an "over-inflated" tire would be one that exceeds the vehicle manufacture's recommended air pressure.

Resorting to sarcasm will not change the facts and real world experience which trump classroom theory every time.

The amount of money and time thrown at an idea does not make it true.

I've read extensively on this topic before I engaged in the practice myself. Over the course of 2 1/2 years I went from a practice of car manufacturers recommended psi, to tire manufacturers max side wall, to a little more. Now I am always around 50 psi. I am not the authority on this topic by any means, but I know what is true and what is not from seeing peoples real world results and from my own experience. If you have an open mind and really want to learn something, go and talk to real world experts at cleanmpg. They are a very mature group who present their actual experiences to you and explain why they have achieved those results.

Also the higher the PSI, the more mositure is in the tire which will start to break down the inside of the tire at a faster rate. This extra moisture will also reduce the life of your TPMS.

My winter tyres Yokohama 185/65 R15 have 36psi and my sommer tyres Yokohama 205/45 R17 have 39 psi.
